Abstract

For threading an inked ribbon through guides and securing it to either a supply spool or a take-up spool, there is provided an attachment having a handle portion and a clamping portion engaging the ribbon. At the edges of the handle portion are flanges which are received snugly between the flanges of the supply spool for holding the ribbon from unwinding. An operator grasps the handle portion to remove the attachment from the supply spool and then threads the ribbon through the guides. Formed in the take-up spool is a T-shaped socket opening through one end of the spool hub. The central portion of the socket also opens along its side through the winding surface of the hub. A securing of the ribbon to the take-up spool is effected by merely inserting the clamping portion of the attachment into the socket.

Ribbon Attachment

For threading an inked ribbon through guides and securing it to either a supply spool or a take-up spool, there is provided an attachment having a handle portion and a clamping portion engaging the ribbon. At the edges of the handle portion are flanges which are received snugly between the flanges of the supply spool for holding the ribbon from unwinding. An operator grasps the handle portion to remove the attachment from the supply spool and then threads the ribbon through the guides. Formed in the take-up spool is a T-shaped socket opening through one end of the spool hub. The central portion of the socket also opens along its side through the winding surface of the hub. A securing of the ribbon to the take-up spool is effected by merely inserting the clamping portion of the attachment into the socket.

The clamping portion of the attachment includes a comparatively wide end portion which bends upwardly to clamp the ribbon between itself and a narrow shank portion extending between the wide end portion and the handle portion. The end portion is received in the horizontal part of the T-shaped socket, and the shank portion fits loosely, in the central part of the socket which opens through the winding surface. When the ribbon becomes worn out and needs replacing, all of the ribbon, except for a section extending between the spools, is wound onto the supply spool. The handle portion of the attachment is then forced out radially from the take-up sp...
